It would be convenient for tools if the receiver of a named interface type had the named type, instead of a copy of the underlying type, which is unwieldy and loses information. There's an existing TODO in types.NewInterface to this effect.

This feature could be supported in a backward-compatible way by adding a SetReceiver(*types.TypeName) method to *types.Interface.

See output of http://play.golang.org/p/WOgHkrUr16 (when run locally) for example:

         type fmt.Stringer interface{String() string}
                 func (interface).String() string
                         interface{String() string}   <--- ideally this would print "fmt.Stringer"
